Under the action of the controller 4, the motor 111 can be started and stopped at proper time, when the motor 111 is started, the motor 111 drives the fourth bevel gear 112 to rotate, the fourth bevel gear 112 drives the fifth bevel gear 113 to rotate, the fifth bevel gear 113 drives the main shaft 114 to rotate, the main shaft 114 drives the conveying disc 115 to rotate, the test tube to be cleaned is conveyed below the test tube brush 31, and the cleaned test tube is conveyed away. The design of circumferential motion like this can only utilize once motion just can accomplish the transport work to wasing the test tube and waiting to wash the test tube to the space that conveying mechanism occupied has been saved.
As a further improvement of the above solution, the test tube conveying device 1 further includes a radial conveying mechanism 12, the radial conveying mechanism 12 includes a transmission rod 121, an air cylinder 122, and a test tube fastener 123, the conveying tray 115 is provided with a radial mounting hole 1151, the transmission rod 121 is slidably disposed in the radial mounting hole 1151, the air cylinder 122 is located below the conveying tray 115 and drives the transmission rod 121 to move in the radial mounting hole 1151, the test tube fastener 123 is mounted at an end of the transmission rod 121 away from the conveying tray 115, the test tube fastener 123 is a test tube sleeve that is matched with the diameter of a test tube, and an elastic member (not shown in the drawings) is adhered to an inner wall of the test tube sleeve, and the elastic member has certain elasticity and can perform a certain fastening function.
Under the effect of controller 4, cylinder 122 can start and close in good time, when needing to give the test tube that waits to wash the additional washing liquid, and controller 4 control cylinder 122 starts, and cylinder 122 drives drive transmission pole 121 and slides in radial mounting hole 1151 to drive test tube fastener 123 motion will wait to wash the test tube and send into the confession liquid control valve 22 below. So design, can set up washing liquid supply mechanism 2 and test tube washing mechanism 3 with same side save space.
As a further improvement of the above scheme, the driving rod 121 is provided with a return spring 1211 and a limit plate 1212, one end of the return spring 1211 abuts against one surface of the limit plate 1212, which is far away from the axis of the conveying disc 115, and the other end of the return spring 1211 abuts against an inner wall of the radial mounting hole 1151, which is far away from the axis of the conveying disc 115, and the limit plate 1212 is fixedly disposed at one end of the driving rod 121, which is close to the axis of the conveying disc 115, and the lower end of one surface of the driving rod, which is close to the conveying disc 115, abuts against the push rod of the air cylinder 122.
When the cylinder 122 is activated, the pushing stopper plate 1212 moves and compresses the return spring 1211. When the cylinder 122 is closed, the elastic force of the return spring 1211 pushes the stopper plate 1212 to move, the stopper plate 1212 drives the transmission rod 121 to move, and the transmission rod 121 drives the test tube fastener 123 to move, so that the test tube to be cleaned can be brought under the test tube brush 31 again to wait for cleaning. This can reduce the on time of the cylinder 122.

After the cleaning liquid supply mechanism 2 adds the cleaning liquid to the test tube to be cleaned, the servo motor 321 rotates forward under the control of the controller, the servo motor 321 drives the third bevel gear 322 to rotate in the same direction, the third bevel gear 322 drives the second bevel gear 323 and the third bevel gear 324 to rotate, the second bevel gear 323 and the third bevel gear 324 are coincident in axial line and opposite in rotation direction, the second bevel gear 323 rotates the outer shaft 325 in the same direction, the outer shaft 325 rotates the inner shaft 326 in the same direction, the inner shaft 326 rotates the nut 3271 of the ball screw 327 in the same direction, the third bevel gear 324 drives the screw rod 3272 of the ball screw 327 to rotate in the same direction, the nut 3271 and the screw rod 3272 rotate in opposite directions, thereby causing the nut 3271 to move downward along the screw 3272, the nut 3271 moving the inner shaft 326 downward, and the inner shaft 326 moving the tube brush 31 downward. When the tube brush 31 is moved to the proper position, the tube cleaning is started. At this time, the servo motor 321 starts to rotate in the forward and reverse directions repeatedly under the control of the controller 4, so that the test tube brush 31 moves up and down while rotating in the test tube, thereby enhancing the cleaning effect. After the test tube is cleaned, the servo motor 321 is controlled by the controller 4 to rotate reversely, so that the test tube brush 31 is lifted. When the test tube brush 31 reaches a proper position outside the cleaned test tube opening, the servo motor 321 stops running. By the design, when the work of cleaning the test tube is realized by only one mechanism, the action of automatically passing the test tube brush 31 in and out of the test tube to be cleaned is realized, and the test tube brush cleaning device is simple in structure and strong in functionality.
As a further improvement of the above solution, a clearance hole 3262 is formed at the top of the inner shaft 326 along the axial direction to prevent interference with the screw 3272 when the inner shaft 326 moves upward during cleaning.
